The lower portion of the oneof the beveled faces 22, 23 and 24 is said magazine as seen from thefront (Fig. effected by merely loosening the said wheels 40 1) issemi-circular in order that a circular 21 and 25 and moving themlongitudinally bucketed feed wheel 4 (hereinafter particuof theirrespective shafts until the wheel 21 larly described) may be rotatedtherein with engages with the face required. to give the itscircumference nearly in Contact Wl h desired speed of the bucketed feedwheel, the inner surface of magazine; and the said and then tighteningthe wheels by means 45 ortion as seen from the side, as in Fig. 2, f theset s rews in their hubs.

is tapered toward the bottom. By thls con- 27 i a ti l haft jo rn l d ith struction, the seed deposited in the magazine frame 1, and also inthe magazine 3, which collects about the lower buckets of the feedreceives its rotation from the shaft 17 wheel and in the rotation of thesame are through the medium of gear wheels 29 and 50 entirely filledwith seed. 30; and at its upper end it is fitted with a 5 is a hopperinto which seed in bulk is head 31 to which the measuring cup 33 isthrown, the same having a pipe a leading attached in a mannerhereinafter described. therefrom to the bottom of the magazine In therevolution of the measuring cup it where it is shaped to correspond withthe passes under the funnel 9 and receives a 55 surface of the magazineat that point, as charge of seed which is carried over a chute 35 intowhich it is dumped by the inversion of the cup in a manner hereinafterdescribed.

It is desirable that the seed measuring cup 33 should rest or slow upfor a short period while under the funnel 9, to insure its being filled;and to obtain this stop, the gear wheel 29 is of the mutilated order, ordevoid of teeth for a proper circumferential distance; and the spacethus produced in the said wheel is arranged to meet the wheel 30 at thetime that the measuring cup is directly beneath the funnel 9.

36 is a scraper preferably of sheet rubber, suspended from the side ofthe funnel 9 under which the filled measuring cup passes. By means ofthis device any seed in the cup which projects above its edge, is sweptoff before the seed is dumped into the chute 35.

To effect the inversion of the measuring cup so that it will dump itscontents into the chute 35 and then right itself before again reachingthe funnel 9 to receive another charge of the seed, the head 31 and thevertical shaft 27 are bored to receive the bar 37 in two parts 9 and hwhich parts meet at o. The upper part 9 of the bar 37 where it iscontained within the head 31 is provided with rack teeth as shown inFig. 4, and these teeth are in mesh with the teeth of a pinion 39inclosed within a cavity in communication with the bore of the head. Theshaft of this pinion extends laterally through the head and to its endis fastened an arm 40 which is secured to the stem 42 carrying the seedmeasuring cup. The lower end of the upper part 9 of the bar 37 isprovided with a pin 43 which extends through a slot j in the hollowshaft 27, and upon the said shaft, and between the projecting ends ofthe pin 43 and the under-side of the upper bearing for the shaft whichis formed as a part of the magazine, is coiled a compressed spring 44.The efiect of this coiled spring is to yieldingly hold down the part 9of the bar 37 in its lowest position and retain the measuring cup duringthe main portion of its revolution in its upright position shown inFigs. 1 and 2, wherein it is adapted to receive seed delivered from thefunnel 9, and carry the same to the chute 35 into which it is dumped bymeans of mechanism hereinafter described.

The lower end of the lower section it of the bar 37 is made polygonaland is guided by a properly supported bracket 45, and it is consequentlynot susceptible to rotation; and at a point between the said bracket andthe beveled gear wheel 30 it is provided with rack teeth similar tothose of the upper section 9.

47 is a toothed sector on a horizontal shaft 49 supported by thebrackets 50 which also support the shaft 17, the teeth of which sectorare in mesh with the rack teeth of the lower section it of the bar 37;and on the shaft 49 is also an arm 52 carrying a roller 0 which bearsagainst a cam 53 on the shaft 17.

The shape of the cam 53 is such that as the seed measuring cup in itsrevolution reaches the chute 35, the bar 37 is suddenly lifted, the seedmeasuring cup inverted and its contents dumped into the chute. After thecup has discharged its measured quantity of seed to the chute 35, it isimmediately righted, and upon again passing under the funnel 9 receivesanother supply of seed.

The lower end of the chute 35 is provided with a nozzle 55 adapted toreceive an envelop held over it by hand, during the dumping operation ofthe machine.

56 is a hinged door in the front of the seed magazine to give access toits interior. In Fig. l the door is supposed to be open, the edge andthe hinges only being shown.

57 is a sliding door which forms the bottom of the seed magazine 3, tobe opened for the discharge of any seed left in the machine upon thecompletion of its operation.

The seed measurin cup 33 is extensible and contractible in efiectivelength to alter its capacity, by means of a movable bottom is held by aset screw which extends through a slot in the wall of the cup as shownin Fig. 5.

I claim as my invention,

1. In a machine for measuring and packaging seed, a seed magazine, afunnel, and a rotary bucketed feed wheel adapted to elevate seed fromthe magazine and discharge it into the funnel, combined with a chute, aseed-measuring cup with means whereby it is revolved in a horizontalplane and made to pass under the said funnel to receive seed from thesame, and devices to invert the said cup and thereby dump its contentsinto the chute, substantially as specified.

2. In a machine for measuring and packaging seed, a seed magazine, afunnel, and a bucketed feed wheel to elevate seed from the magazine anddischarge it into the funnel, combined with a chute, a revoluble seedmeasuring cup adapted to receive the seed from the funnel, mechanismwhereby the said seed-measuring cup is inverted at the time that it isabove or over the chute, and a feed hopper with a delivery pipe leadingtherefrom to near the bottom of the magazine, the said pipe beingadjustable in height whereby the quantity of seed delivered from thehopper to the magazine may be varied, substantially as specified.

3. In a machine for measuring and packaging seed, a seed magazine, afunnel, a device to elevate seed from the magazine and discharge it intothe funnel, and a chute, combined with a measuring cup, devices wherebythe said cup is revolved horizontally about an axis which is exterior ofthe the funnel to insure of its being filled with seed, and othermechanism to effect the inversion of the cup while the same is over thechute, substantially as specified.

4. In a machine for measuring and packaging seed, a frame, a seedmagazine which is supported by the frame, a funnel, a feed Wheel toelevate seed from the magazine and discharge it into the funnel,combined with a chute, a revoluble seed measuring cup, mechanism wherebythe seed measuring cup is revolved about an axis, other means to invertthe cup when the same is above or over the said chute, and differentialgear wheels to drive the feed wheel, whereby the speed of the feed wheelwith respect to that of revolution of the measuring cup about its axiscan be varied, substantially as specified.

5. In a machine for measuring and packaging seed, a seed magazine, ahorizontal rotary shaft carrying a bucketed wheel which is situatedWithin the magazine and adapted in its rotation to elevate and dischargethe seed contained in the magazine, combined with a bevel gear wheelsecured to the shaft of the bucketed wheel and adapted for adjustmenttoward and from the said feed wheel, the said gear wheel having amultiplicity of toothed faces of different diameters, and a verticaldriving shaft carrying a bevel gear wheel having a single toothed face,which beveled gear wheel is adjustable longitudinally of the said shaft,whereby the teeth of the second wheel can be brought into mesh with theteeth of any one of the toothed faces of the first wheel, to change therelative speeds of the bucketed feed wheel and the driving shaft,substantially as specified.
